3 to 5: Moderate

A UV Index reading of 3 to 5 means moderate risk of harm from unprotected sun exposure.

• Stay in shade near midday when the sun is strongest.

• If outdoors, wear protective clothing, a wide-brimmed hat, and UV-blocking sunglasses.

• Generously apply broad spectrum SPF 30+ sunscreen every 2 hours, even on cloudy days, and after swimming or sweating.

• Watch out for bright surfaces, like sand, water and snow, which reflect UV and increase exposure.
